cxa demangle /Engine/Source/ThirdParty/Android/cxa_demangle/ 2016-04-12T19:25:57.3258913-04:00 UE needs callstack printing when running on Android devices and we need this function to convert a mangled function name into a human-readable one.  UE links with cxx-stl from stlport, but that doesn’t include the abi::__cxa_demangle function in the library. The gnu-libstdc++ libraries also included with the NDK do include this function, but we don’t link against gnu-libstdc++ and don’t want to do so just for this function. The easiest solution is to compile the __cxa_demangle source code file and link it manually. https://android.googlesource.com/platform/external/libcxxabi_35a/+/master/LICENSE.TXT Licensees Git P4 /Engine/Source/ThirdParty/Licenses/CXADemangle_License.txt
